Create or modify the eclipse.ini file in the user settings location and add the new memory arguments. For example:

After adding the new memory thresholds every DVT instance will use them. If you want to change the memory only for a single invocation of DVT you can use the dvt.sh arguments (-heap_size corresponding to -Xmx and -stack_size corresponding to Xss) in the command used to invoke DVT.

To share this configuration with other users you can put the eclipse.ini file in common location. Users will still be able to change the settings using an eclipse.ini in the user location.
